NEW JERSEY.

JERSEY, A CORPORATION OEE SHADE ROLLER.

Application filed August 7, 1923. Serial No. 656,186.

To all whom it may concern:

Be it known that I, STEWART H. HARTS- HORN, a citizen of the United States, and a resident of Short Hills, county of Essex, and State of New Jersey, have invented a certain new and useful Shade Roller, of which the following is a specification.

The invention relates to tubular shade rollers, known as tin rollers, and more particularly to means for adjusting such rollers whereby they may be made to fit window frames: of various widths.

The objects of the invention are to produce such a roller which will be cheap to construct, and which may be adjusted as to length to very minute degrees whereby the same may be made to accurately fit the window frame to which it is applied.

These and further objects will more fully appear in the following specification and accompanying drawings considered together or separately.

One embodiment of the invention is illustrated in the accompanying drawings, in which like parts in all of the several figures are designated by corresponding characters of reference, and in which- Fig. 1 is an elevation of a shade roller embodying the invention.

Fig. 2 is a longitudinal section, partly in elevation of the same, the section being taken on the line 2-2 of Fig. 1.

Fig. 3 is a cross section on the line indicated by 3-4 of Figs. 1 and 2 showing the parts unsecured.

Fig. 4 is a similar view showing the parts in clamped relation, and

Fig. 5 is a fragmentary elevation of a modification.

In the drawings 1 designates a, tubular metal roller distorted to form the usual longitudinal groove 2 by means of which a shade may be secured to the roller. 1

A relatively short section 3 of tubing of the same configuration as the tube 1 is provided, and the section 3 carries a wooden extension plug 4 of cylindrical cross section. The diameter of the plug 4 is such that it may be easily inserted into the tubes 1 and 3, and is provided with a longitudinal peripheral groove 4.

In the embodiment of the invention illustrated a short tube 5 telescopes in the outer end of the tube 3, and a cushioning spring the tube 5 and the plug whereby the end of the tube 5 may be moved inward to permit of the roller being placed in position, when the ex pansion of the spring will retain the pintle 7 in position in its bracket.

Instead of employing the tubes 3 and 5, the cap carrying the pintle 7 may be secured tie the outer end of the plug 4, as shown in A kerf 9 is cut in the plug from one end nearly to the other. The kerf cuts through the center of the plug and is preferably perpendicular thereto. At one edge, as it were, of the kerf, the material of the plug is removed to form a relatively wide and shallow groove 10.

The tubular roller 1, near the end thereof, is punched, as at 11, to form a countersink adapted to receive the head of a wood screw 12. The countersink is preferably spaced 90 from the groove 2, and is in alinement with the groove 10 and the kerf 9.

The plug 4 is inserted in that end of the tube 3 opposite the tube 5, with the metal forming the groove 8 in the groove 4 and is secured with its kerfed end extending therefrom, by means of a brad 13 driven through the tube 1 and into the plug.

In assembling the roller, as a whole, the kerfed end of the plug is inserted to the depth desired, in the open end of the tube 1, the distortion forming the groove 2 resting within that portion of the groove 10 which is within the tube 1 whereby a con tinuous groove 24 -8 will extend the entire length of the roller. The screw 12 is inserted in the opening formed by the punched countersink 10 with its gimlet end in the kerf 9. A screwdriver is applied and the screw is driven home. As the body of the screw enters the kerf, the latter will be widened, and the two semicylindrical sides of the plug will be expanded into intimate engagement with the bore of the tube 1, and the extension composed of the plug 4 and the tubes 3 and 5 will be firmly retained in position relatively to the tube 1.

By means of the kerf 9, the closest adjustments within the limits of the kerf, may be made.

Because of the fact that the tube 1 cannot be placed over the plug unless the grooves 2 and 4 are in alinement, and the further fact that the groove 2 is the same radial distance from the countersink as are the grooves 45 and 10, the parts will always be assembled in proper position.

If desired the tubes 3 and 5 may be. omitted and the pintle 7 be carried on the outer end of the plug 4.

In accordance with the provisions of the patent statutes the principle of the invention has been described, together with the apparatus which is now considered to represent the best embodiment thereof, but it is desiredto have it understood that the apparatus shown is merely illustrative, and that the invention may be carried out in other ways.

The invention having been described, what claimed as new and desired to be secured by Letters Patent of the United States, is

1. A shade roller, comprising a plurality of tubular members, and an element secured within the bore of one member and projecting axially therefrom, the other of said members being adapted to receive the projecting portion of the element in its bore, and means accessible from outside the member for expanding the element to engage the bore of said member.

2. A shade roller, comprising a plurality of tubular members, and an element secured within the bore of one member and projecting axially therefrom, the other of said members being adapted to receive the pro jecting portion of the element in its bore, and means for expanding the element to engage the bore of said member, said means acting to secure the n'ieinber to the element.

3. A shade roller, comprising plurality of tubula members, there being depressionin the wall of each member to form a groove in and extending longitudinally of the member, an element secured within the bore of one member and projecting axially therefrom, the other of said members being adapted to receive the projecting portion of the element in its bore, and means accessible from outside the member for expanding the element to engage the bore of said member, said, means a ting to secure the member to the element.

4. A shade roller, comprising a tubular cylindrical member, a cylindrical element. adapted to penetrate the bore of the memher, and means accessible from outside of theimember-for expanding the element into intimate engagement with the inner surface of the member 5. A shade roller, comprising atubular cylindrical member, a cylindrical element adapted to penetrate the bore of the member, and means accessible from outside of the member for expanding a portion of the element into intimate engagement with the inner surface of the member.

6. A shade roller, comprising a tubular cylindrical member, a cylindrical element adapted to be inserted axially within the bore of'the member, that portion of the element within the member having a longitudinal kerf therein, and means accessible from outsidethe member when the latter is in proper position on the element for engaging the kerf and expanding the kerfed portion of the element. into intimate engagement with the inner surface of the member.

7. A shade roller, comprising a tubular cylindrical member, a cylindrical elemem adapted to be inserted axially within the bore of the'member, that portion of the element within the memberhaving a longitudinal kerf therein, and a screw passing through the wall of the member and engaging the kerf for expanding the kerfed portion of theelement into intimate engagement with. the inner surface of the member.

8. A shade roller, comprising a tubular Cf lllKll'lCll member, there being a perform tion in the wall of the member, there being a. depression in the member to form a longitudinally extending groove in the outer surface of the member,'a cylindrical element adapted to be insertedaxially in the hor of the member, there being alongitudinal grows in the element adapted to receive the depressed; portion of the member, there being a longitudinal kerf cut into the member and separating one end ofthe member into two tines, said kerf and said perforation in the member being so arranged that when the element is inserted in the member the perforation will-be in alinement with the kerf, and a screw passing through they perforation and entering the kerf to expand the bifurcated portion of the element into intimate engagement with the inner surface of the member.

This specification signed and witnessed this 3rd day of August, 1923.
